The Pivers Island Coastal Observatory (PICO) weekly (and sometimes more) time-series turned eight today. Started in 2010 as an undergraduate independent student project focusing on ocean acidification, the coastal time-series has matured into a long term coastal sentinel, observing seasonal, yearly and interannual changes in the physics, chemistry and biology of the coastal marine environment with weekly sampling. Additional offshore longitudinal sampling (PICO-LOVE) provides spatial context. Data is available through BCO-DMO. Happy Birthday and hooray for PICO!
